Hello All,
I am wondering if any of you have experience using the parallel computing toolbox, specifically with webread. I am currently working on a program to download, and process google finance data. Everything is going great, however the download time for aournd 300 stock stymbols is rather long. I am interested in speeding this up, and thought webread might be a good option. For example, here is a simplified version of the code I am looking to speed up.
%General set of tickers, usually 250+ in length
tickers={'AAIO','AAPL','FB','GOOGL','NVDA','TWTR'}Length='10';Freq='60';for ii = 1:length(tickers) wop=weboptions('Timeout',15); temp=webread(strcat('https://www.google.com/finance/getprices?i=',Freq,'&p=',Length,... 'd&f=d,o,h,l,c,v&df=cpct&q=',tickers{ii},'&ignore=.csv'),wop); data = textscan(temp, '%s%f%f%f%f%f%f', 'delimiter', ',', ... 'Headerlines', 7); min=str2double(data{1}); min(isnan(min))=0; op=data{2}; high=data{3}; low=data{4}; cl=data{5}; vol=data{6}; stocks(ii).ticker=tickers{ii}; stocks(ii).min=min; stocks(ii).op=op; stocks(ii).high=high; stocks(ii).low=low; stocks(ii).cl=cl; stocks(ii).vol=vol;end
To clarify, I do not currently own the parallel computing toolbox, I am just wondering if it may help my particular situation.
